Leadon told the band about Felder, who sat in with them at least once, and that made Felder an easy hire, and later, an easy fire.
Based on at least one story (the Alan Cranston fiasco) that Frye told, IOW, just getting his side of it, I’d conclude that Frye was a total *******.
I could be wrong but didn’t Felder have a hand in writing the music to Hotel California, I seem to remember he was instrumental in developing the song versus just performing it on stage
